Located in Peterborough, Ontario, Canada, Bryston manufactures refined high-end audio amplifiers, preamplifiers, loudspeakers and other superb audio equipment for the discerning audiophile.

Regardless of how good any individual component specs out, your audio system will only perform as well as the weakest component in the system. The best exotic loudpeakers available will sound mediocre when driven by a gutless power amplifier. Likewise, a powerful, expensive, accurate amplifier driving cheap, poor quality speakers will sound cheap. Superb audio systems are assembled by collecting superb components. When it all finally comes together, you know it!
